Dry Cough
Over the counter relief options
Is it a dry cough?
A dry cough is a persistent, tickling, or scratchy cough that produces little to no mucus or phlegm. It is often triggered by inflammation or irritation in the throat and upper airways rather than an underlying buildup of mucus.
Dry coughs are commonly associated with viral infections such as the common cold or flu, but they can also be caused by allergies, exposure to dry air, asthma, or even irritants like smoke, dust, and perfumes.
Many people also experience hoarseness, throat soreness, or disrupted sleep because the cough tends to flare up at night.
While usually harmless and self-limiting, a dry cough can be very disruptive to daily activities, work, and rest. Recognizing the type of cough is a key to recovery.

Pro tips and selection criteria​
Choosing the right product is based on symptoms, age and other factors that you need to consider to achieve the best relief results.​​
Dextromethorphan tablets/gel capsules
Dextromethorphan is a cough suppressant that works by calming the cough reflex in the brain. It is best suited for dry, non-productive coughs with little to no mucus. Gel capsules may begin working faster than tablets due to quicker absorption.
Tip: Short-acting forms are convenient for daytime use and can be taken as needed throughout the day. Avoid using if your cough becomes productive or mucus develops.
Dylsem 12-hr cough liquid
This extended-release form of dextromethorphan provides long-lasting cough suppression for up to 12 hours. It helps control dry, non-productive coughs throughout the day or night with fewer doses.
Tip :Choose a 12-hour formula if you want consistent, all-day relief without the need for frequent dosing—especially helpful for workdays or overnight use.
Robitussin Soft Chews Nighttime
These chewable tablets combine dextromethorphan, a cough suppressant, with doxylamine succinate, a sedating antihistamine. Together, they help suppress a dry cough while promoting drowsiness, making them well suited for nighttime use.
Tip: Use only at bedtime. This formula can significantly cause drowsiness, so avoid daytime use, driving, or operating machinery after taking it.
Nighttime Cough Syrup (Cherry Flavor)
This liquid nighttime formula combines dextromethorphan, a cough suppressant, with doxylamine succinate, a sedating antihistamine. It helps suppress dry coughs while promoting drowsiness to support restful sleep.
Tip: Use at bedtime only. This option is especially helpful if you prefer liquids over tablets or chewables. Avoid daytime use, driving, or operating machinery due to drowsiness.
​
Chest Rubs
Chest rubs are topical ointments that release soothing vapors to help ease coughing and improve breathing comfort. They are commonly used at night to provide gentle relief from cough-related discomfort.
Tip : apply to the chest or back before bedtime for aromatic, non-oral relief. Chest rubs can be used alongside oral cough medications for added nighttime comfort.
Child-Safe Formulas
Some medications are designed to be child-safe formulas to avoid overdosing and side effects that could happen if you use adults' formulas​.
Children’s Delsym®
Children’s Delsym® is a 12-hour, extended-release cough suppressant designed to relieve dry, non-productive cough in children ages 4 and older. It contains dextromethorphan to help reduce coughing for long-lasting relief.
Tip: Use only in children over 4 years of age and follow package dosing carefully. Mild drowsiness may occur. Avoid combining with other products that contain dextromethorphan.
​
Throat Soothing Lollipops
Throat-soothing lollipops are non-medicated, kid-friendly pops designed to ease mild throat irritation and dryness. They provide gentle moisture and comfort, making them a good option for children who do not tolerate cough syrups.
Tip: Use as needed for throat comfort. These pops do not suppress cough reflexes but can help calm throat irritation that triggers coughing.
​
Honey Cough Syrup Daytime
This honey-based cough syrup provides natural relief for mild cough and throat irritation. Honey helps coat and soothe the throat, which may reduce coughing without the use of strong medications.
Tip: Typically non-drowsy and suitable for daytime use. Do not use in children under 1 year of age due to the risk of infant botulism.
​
Which One Should You Choose?
-
Daytime dry cough: Start with dextromethorphan (such as Robitussin® or Delsym®) for effective, non-sedating relief.
-
Nighttime cough: Night formulas with doxylamine can help suppress coughing and promote sleep. Avoid daytime use due to drowsiness.
-
Children: Use only age-appropriate syrups, honey products (not for children under 1 year), or throat soothers. Adult formulas are not safe for kids.
-
Extra comfort: Chest rubs are a helpful add-on for nighttime relief.
Important:
Avoid cough suppressants if mucus or phlegm is present, as they can make chest congestion harder to clear. Use caution with sedating products if driving or operating heavy machinery.
